Agoraphobia is a normal response to anxiety and self-defense. When we feel threatened, we would like to retire somewhere safe, like a turtle in its shell.
During anxiety it’s very important to establish control over such a reaction. Avoiding the situation is not an effective way of dealing with agoraphobia!
Agoraphobia can be very exhausting and one of the most severe anxiety symptoms. Do not stop going out. If it starts to develop you will quickly see that every time you need to deal with the outside world you will get panic attacks.
The panic you can catch even because of the thought of needing to go out. Using the tactics of diversion, which I recommend, you will learn how to get back into the world and how to enjoy it when you do.
This takes practice and time, but it can be done.
